Question

You are given a sample of an unknown solution and are tasked with determining the density. The solution is miscible with water, so you cannot use a float test. To complete this task, you begin by obtaining a clean dry beaker and measure its mass on a balance (120.3621 g). You then use a pipet to transfer the liquid into the beaker. The initial reading on your pipet is 4.126 mL and after you have dispensed the liquid the pipet reads 6.518 mL. You then obtain the mass of the beaker with the liquid inside (123.0194 g).
_____g/mL

Answer 1

Answer: 1.11 g/mL

Explanation:

Density = mass/vol

mass 123.0194-120.3621g = 2.6574

vol 6.518-4.126 ml = 2.392
